Glass Fuse 800mA 250V AC Pack 5
These EATON BUSSMANN GMD-series glass fuses protect circuits rated up to 250 V AC with an 800 mA time-delay element. They suit technicians and hobbyists maintaining equipment that specifies a 20 mm × 5 mm cylindrical fuse. The pack of five provides ready spares for service kits or bench stock.
Time-Delay Element 100A 250V AC 10kA 125V AC
The single-element time-delay characteristic withstands brief inrush currents without nuisance opening while still interrupting 100 A at 250 V AC and 10 kA at 125 V AC. CE, CSA Class 1422-01 and UL 248-14 listings confirm compliance for industrial and consumer gear. Non-rejection body style fits standard HTB-series fuse blocks.
20mm Length 5mm Diameter Glass Body
Physical size is the decisive specification: the fuse measures 20 mm long by 5 mm diameter with a glass body. Verify the holder and panel cut-out match these dimensions before ordering. Buyers who need a different length, diameter or ceramic body cannot use this part.

Questions about this item
Does the 5 mm diameter glass body need any periodic inspection or replacement beyond its single use?
The fuse is a single-element, non-rejection design rated 800 mA at 250 V AC; once it interrupts a fault it must be replaced, and no scheduled maintenance is required for the glass body itself.
What is the first electrical limit reached during a sustained overload on the 250 V AC rating?
The 100 A interrupt rating at 250 V AC is the limiting factor; the fuse will open before current exceeds that level under continuous overload conditions.
How much heat does the cylindrical glass fuse generate when running at 800 mA all day?
At its rated 800 mA the time-delay GMD fuse operates within its design temperature rise; the glass body and 5 mm diameter are sized to dissipate normal load heat without additional cooling.
